Several naturalists, especially Colonel Hamilton Smith, thought 
they had observed a diiference in the horns of the Russian and 
American Elks; I have compared numerous specimens from both 
countries, but can discover no appreciable distinction between 
them. 
The Elks, like most of the other Deer, and especially of the 
animals which inhabit the cold and mountain regions, present a 
very considerable difference in size, according to the scarcity or 
abundance of the food which the locality they imhabit affords ; 
and the development of the horns appears to be greatly imflu- 
enced by this cause, so that the horns of the animal inhabiting 
the more barren districts are much less developed than those 
found in more fertile situations, and I think I have observed this 
to be the case with both the Russian and the American horns; 
but on this head naturalists are hkely to be much misled, as the 
horns which are imported are generally chosen for their size and 
perfect development, and the small and less-developed speci- 
mens are only to be observed in the cargoes of horns which are 
imported for economic purposes. 
These observations are equally applicable to the Rein Deer.
